Since I'm calling `(require 'general)` in `wpc-package.el`, which gets called at
the beginning of my `init.el` file, all sub-modules have `general`. I originally
wanted this, but I'm beginning to rethink that preference.
After `script.el` broke my CI because of a missing `general` dependency, I'm
fixing it for `buffer.el` and all other modules that consume `general`.
